SPECIFICATION forming part of Letters 'Patent No. 453,971, dated J' une9, 1891.

Applicationfiled Octob'er 29, 1890. Serial No. 369,697. (No model.)

To all whom, if; may concern:

Be it known that I, HARRY C. GOODRICH, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvements inSchool-Slates, of which the following is a specification.

The aim of my invention is to provide a slate With a cheap and durablemuffler or cushion whichl shall protect the frame not 1o only upon itsside faces, but also on the outer edges; and to this end it consists ina frame provided with a series of notches in its edge and With atape-like strip or ribbon Woven back and forth through the notches fromone face of the frame to the other in such manner that it is exposedalso at the edge of the frame. The grooves or slots may be varied inform, number, and arrangement at Will, and the strip Woven therethroughin various Ways zo Without departing from the limits of my invention.

In the accompanying drawings, Figure lis a perspective view of a slateprovided with my muffler. Fig. 2 is a perspective View of one side ofthe notched frame as it .appears before the mufing-strip is applied.Fig. 3 is a cross-section on the line 3 3 of Fig. l. Fig. el is aperspective View showing the frame and muffler in another form. Fig. 5is an 3o edge view showing the frame of the preceding ligure as itappears prior to the application of the strip.

In each of the figures, A represents a frame of Wood or other suitablematerial applied to 3 5 and encircling the slate proper, as usual. Inpreparing the frame to receive the muffler I saw or otherwise cutthrough its outer edge from face to face a series of slots a. In Figs. land 2 these slots are at equal distances 4o apart and at right angles tothe faces of the frame, While in Figs. 4: and 5 the slots are arrangedin positions oblique to eachother and to the face of the frame.

The muffler consists of a tape-like strip or 4ribbon B, of Woven fabric,felt, rubber, leather, or other soft and strong material. In Fig. l itis inserted edgewise into the slots, being Wound back and forth in suchmanner that it extends along and rests upon one face of the frame for ashort distance, then extends 5o through the same along the oppositeface, thence through a second slot to the first surface, and so onrepeatedly, while at the same time its outer edge is permitted toproject slightly beyond the edge of the frame.

In Figs. Il and 5 the application of the strip is of the same characteras that above described, but owing to the position of the grooves a moreextended or, in other Words, more nearly-continuous covering of the sideoo faces is effected.

The muflier above described presents an ornamental appearance. It iswell adapted to resist Wear, and if Worn or loosened at one pointremains fast at all other places.

A single strip may be extended entirely around the frame or a separatestrip used in each of its edges. The extremities arcsecured by tuckin gthem tightly intothe notches. The strip may be secured in place by glueor 7o other adhesive material, or, if drawn tightly into the notches, itmay be successfully used without being otherwise fastened.

Having thus described my invent-ion, what I claim is- 75 1. Aslate-frame having notches throughits edge from face to face, incombination With a mufliing-strip Wound back and forth through thenotches from one face to the other and exposed beyond the side faces andedge of the 8o frame.

u 2. A slate-frame having notches therethrough from one face to theother, in combition with a tape-like muiTling-strip Wound to and frothrough the notches and over the faces of the frame and glued in placetherein.

In testimony whereof I have hereunto set my hand this 7th day ofOctober, 1890, in the presence of two attesting witnessesy HARRY C.GOODRICH.
